ELECTRIC SlG NALlNG AFPARATLJS` SPECIFICATION forming part of Letters Patent No. 669,999, dated March 19, 1901. Application iiled May 1900. Serial No. 17.920?. (No model-l To a/ZZ- w21/0.17?, t '1n/tty concern: n

Be it known that I, ADOLF MENSING, a subject of the Emperor of Germany, residing atl Berlin, Germanyhave invented a certain 5 new and useful Improvement in Electric Signaling Apparatus, of which the following is a specication. Y

My invention relates'to electrical signaling apparatus, and has for its special object to 1o produce a signaling-apparatus which may be employed in submarine work and in mines and for other purposes.

To this end a particular feature of the invention is a' circuit-closer comprising an air [5 and water tight' casing and a movable circuittermina-l adapted to bemoved to close the circuit by a jar or blow on the outside of the casing.

In the accompanying drawings I have illus- :o trated two apparatuses embodying my invention, with the understanding, however, that my invention is not limited to these two apparatuses, which are merely shown by way of example. These two apparatuses are but 5 illustrations of the many forms in which my invention may be clothed, the salient features of the invention being pointed out in the claims at the end of this specification. i In the drawings, Figure l is asectional o elevation, partly in diagram, of one form of my invention. Fig. 2 is a View of the rear face of the front plate of the circuit-closing apparatus., and Fig. 3 shows an apparatus embodying a special adaptation of myinvengntion to be employed for measuring the velocity of the flow of submarine currents and the like.

In the drawings, a indicates a suitable water and air tight casing or box, which in the a present instance is provided with a removable front or face-plate b, capable of transmitting the energy of a blow. Thisface-plate is shown as secured to the, box or casing by screws c with the intervening packing d. g Mounted upon theinside face of the face-plate is a suitable ring e of insulating material. This ring carries a suitable contactf and a yspring-contact g, upon which is carried a blockh of` some heavy material, which block is insulated from its supporting spring-contact g. The circuit-wires 't pass through aY packing ring or plug 1c in the side of the box or casing'a'and are sealed water and air tight has been spent,

therein. The conductors j are suitably connected with a bell Z or other annuuciator or alarm device, the battery` m being interpolated iu one 0i' the wires, as i. The wires Q', andjare or may be suitably insulated. It will be observed. that if a blow be struck against the face-plate b the energy of the blow will be transmitted to the block h, which is in contact therewith, andthe said block will be projected rearwardly against the tension of its spring g to bring a contact-point 0, carried 'by the said spring-contact, against the opposing contactf, and thereby close the circuit momen tarily and ring the bell. When the impetus given to the block h by the blow the spring g restores the block h toits initial position. (Shown in Eig. l.) It will be observed that the block 7L need not be ofthe form and character shown; but I intend to include within the term block any solid body capable of oscillating under the impact of a blow delivered against a side of the inclosing casing oithe apparatus, the said inclosing casing consisting in the present instance of the casing a and the faceplate b. In apparatus which is entirely stationary the springg may be dispensed with and `a flexible metallic carrier for the block h sub- The apparatus which I have just described is capable of many valuable uses. The circuit-closingiportion of the apparatus being hermetically inclosed the apparatus may be employed under Water and-in mines or other places where an explosive gas may exist,which explosive gas would be ignited'by thesparks sometimes passing between the terminals of.

an ordinary:circuit-closer.

In Fig. 3 have shown an apparatus especially adapted for ascertaining the velocity of submarine currents, which,as is well known,

frequently flow at a dierent rate and even in a dierent direction from the surface-currents. In this figure the face-plate is diagrammatically indicated at b. In front of this face-plate is a suitable hammern, pivotally mounted at n' and provided with the trip or extension n2. This trip or extension n2 receives the arm p of a bell-crank leverp, which `is pivotally mounted at p2 and provided with a suitable spring q, which bearing against the hammer 'n tends to force the hammer toward the face-plate ZJ. f The bell-crank lever p IOO The operation as follows: Vhen the ap-- paratus is lowered in the water, the currentiiow will cause the shaft fn to be rotated, thereby rotating the cam r. It is to be supposed that at this time the bellcrank lcv'erp rests against the low lportion, r of the drop-cam, and as the cam conti n ues -to revolve the high portion r2 will come against the le ver, thereby swinging the lever to the right and drawing back the hammer n. At the instant that the bell-crank lever p drops from the high portion of the cam to the low portion thereof the spring (1,' whose tension produced the drop of the lever, willlikewise throw the hammer n against the face-plate of the circuit-closer casing, whereby the block 7L will, under the impact of the blow, be driven rearwardly to close the circuit, as described. By properly arranging and proportioning the parts the apparat-us will deliver a number of blows in a minute proportional to the speed of the current-flow, so that by counting the nnmberof closures of the circuit in a minute the speed of current-flow may be directly determined. If desired, the apparatus can operate in an equally satisfactory manner on a normally closed circuit, opening the same when the blow is struck.

' Having described my invention, what claim, and desire to secure by Letters Patent, is-

l. In an electrical alarm apparatus, the

, combination of a closed casing having an exposed side adapted to receive a blow, circuitterminals maintaining a normally open circuit, and a block located within the casing in such proximity to one side thereof as to re-' ceive the impact of a blow delivered theretoand eiecting by its movement a closure of the circuit.

2. ln an electrical alarm apparatus, the combination of a hermetically-closed casing having an exposed side'adapted to receive a blow, circuit-terminals mounted therein normally open-circuited, a block carried by one of the circuit-terminals within the casing and normally in operative proximity to the exposed side of the casing and adapted to receive the impact of a biow delivered against that side ofv the casing and to close the circuit by its movement.

3. In an electrical alarm apparatus, the combination of a closed casing having an exposed side adapted to receive a blow, circuitterminals therein, a lblock in operative proximity with one of the circuit-terminals and l in contact with the-exposed side of the casing and adapted to receive the impact of a blow delivered against the said side and to manipslate the circuit when moving under the impact of the blow.

will cause the block to oscillate and manipulate the circuit.

5. I n anelectrical alarm apparatus, the combination of a closed casing having an exposed sideadapted to receive a blow with means for effecting the opening and closing of a circuit comprised in part by a block mounted in the casing so as to oscillate freely therein and in operative proximity with the exposed side of the casing, whereby a blow delivered against the casing will elect a movement of the block and a manipulation of the circuit. 3

6. In an electrical alarm apparatus, the combination of a closed casing having an exposed side adapted to receive a blow, circuitterminals therein, an oscillating block adapted to effect the opening and closing of the circuit at the circuit-terminals in operative relation with the exposed side of the casing to receive the impact of a blow delivered i against the casing and circuit connections,

receive the im pact of a blow delivered againstA the casing and adapted to effect the openingl yand closing of the circuit at the circuit-terminals and a suitably-actuated means for delivering a blow against said exposed side.

In a signaling device, the combination suitable circuit connections of a closed casing, circuit-terminals carried thereby normally and electrically separated anda freelyoscillating block in operative relation with the lsaid circuit-terminals and with an exposed side of the casing and adapted to be oscillated by the impact of a blow delivered against the said side of the casing.

9. In a signaling device, the combination of a casing, a spring located therein, a freelyoscillating block carried thereby and exerting its tension toward the side of the casing and circuit manipulating means under the control of the block, the block being adapted to be oscillated by the impact of a blow delivered against the side of the casing.-
